... um well firstly only Nintendo sells on Nintendo =P (not entirely true)
Seriously though I bet a lot of those Vita games are of the very niche kind, the kind that actually sell better on Vita than 3DS.
The only other thing that beats it is PS3/4 and looking at PS4's list theirs a lot western games or games with potential in the west (as well as those with potential for both Japan and the west)... also most probaly cant run on a 3DS =P

The Vita games are niche because they are specifically designed for the platform. That's the consequence of the developers' desire to develop for PlayStation. Objectively speaking, they could just as well tailor the games they develop for the 3DS audience in which case the resulting games would be something more normal and diverse, rather than something that exploits a niche. Think of the range of games that Level 5 has put out over the years.

There isn't much Nintendo can do to convince third parties who absolutely want to make PlayStation games. That bias goes as far as openly expressing concern about the future of PlayStation platforms and taking on the responsibility to grow the installed base of Sony's devices (while Sony more or less sits idly by, unwilling or incapable themselves to sell their own systems in larger numbers). IIRC both Nippon Ichi and Square-Enix have said as much rather recently.

The 3DS games are for kid and  avid Nintendo fans because they are specifically designed for the platform. That's the consequence of the developers' desire to develop for 3DS. Objectively speaking, they could just as well tailor the games they develop for the 3DS audience in which case the resulting games would be something more kid friendly and monster hunter esque type of games.
